SECTION XVIII. He who lies under that stony canopy would have taught her another choice, in his day, if she would have listened to him; but he and his counsels have long been forgotten by her, the dust lies upon his lips. Through the heavy door whose bronze network closes the place of his rest, let us enter the church itself. It is lost in still deeper twilight, to which the eye must be accustomed for some moments before the form of the building can be traced; and then there opens before us a vast cave, hewn out into the form of a Cross, and divided into shadowy aisles by many pillars. Round the domes of its roof the light enters only through narrow apertures like large stars; and here and there a ray or two from some far away casement wanders into the darkness, and casts a narrow phosphoric stream upon the waves of marble that heave and fall in a thousand colors along the floor. What else there is of light is from torches, or silver lamps, burning ceaselessly in the recesses of the chapels; the roof sheeted with gold, and the polished walls covered with alabaster, give back at every curve and angle some feeble gleaming to the flames; and the glories round the heads of the sculptured saints flash out upon us as we pass them, and sink again into the gloom. Under foot and over head, a continual succession of crowded imagery, one picture passing into another, as in a dream; forms beautiful and terrible mixed together; dragons and serpents, and ravening beasts of prey, and graceful birds that in the midst of them drink from running fountains and feed from vases of crystal; the passions and the pleasures of human life symbolized together, and the mystery of its redemption; for the mazes of interwoven lines and changeful pictures lead always at last to the Cross, lifted and carved in every place and upon every stonel sometimes with the serpent of eternity wrapt round it, sometimes with doves beneath its arms, and sweet herbage growing forth from its feet; but conspicuous most of all on the great rood that crosses the church before the altar, raised in bright blazonry against the shadow of the apse. And although in the recesses of the aisles and chapels, when the mist of the incense hangs heavily, we may see continually a figure traced in faint lines upon their marble, a woman standing with her eyes raised to heaven, and the inscription above her, "Mother of God," she is not here the presiding deity. It is the Cross that is first seen, and always, burning in the centre of the temple; and every dome and hollow of its roof has the figure of Christ in the utmost height of it, raised in power, or returning in judgment.
